We look at the division of 799005 by 77 
The aim is to understand the frequency of 77 in 799005.

Step 1:
If we divide 7 by 77, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 77

Advancing to step 2:
77 can be fit into 79 1 times, resulting in a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 77 from 79 leaves us with 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 77

Let's proceed to step 3:
The number 77 fits into 29 0 times, leaving a remainder of 29.
The next digit of our result is 0. 
Result so far: 10.0
Deduct 0 from 29 and we're left with 29.
Include the next digit (0) from the dividend after 29, then repeat: 290 / 77

Going ahead to step 4:
77 can be fit into 290 3 times, resulting in a remainder of 59.
Put 3 as the next digit of the answer. 
Result so far: 103.0
If we take 231 away from 290, we end up with 59.
Append the next digit (0) from the dividend to 59 and continue with: 590 / 77

Advancing to step 5:
The number 77 fits into 590 7 times, leaving a remainder of 51.
Put 7 as the next digit of the answer. 
Result so far: 1037.0
The remainder is 51 after subtracting 539 from 590.
Grab the next digit (5) from the dividend, add it to 51, then carry on: 515 / 77

Going ahead to step 6:
515 divided by 77 is 6 with a remainder of 53.
Use 6 as the next digit of our solution. 
Result so far: 10376.0
Deduct 462 from 515 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 7:
When dividing 530 by 77, we get 6 with a remainder of 68.
The next digit of our result is 6. 
Result so far: 10376.6
If we subtract 462 from 530, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 8:
680 divided by 77 is 8 with a remainder of 64.
Put 8 as the next digit of the answer. 
Result so far: 10376.68
The remainder is 64 after subtracting 616 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 9:
The number 77 fits into 640 8 times, leaving a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 10376.688
Subtracting 616 from 640 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final result is 10376.688 with a remainder of 0.0024.
